Patent DE-2159583-A1 (DE)
Title: Mica paper - with high mechanical strength and temp resistance
Inventor: HELING WILHELM
IPC: D21H13/44
Filed: 1971-12-01
Abstract: Material with high mechanical strength and temp. resistance is produced by using a mixt. of polyester fibres and fine mica. After suctioning off excess water, the mixt. is calendered at 190-200 degrees C to soften the thermoplastic fibres and bond them together at their points of intersection, whilst locking the mica platelets in the lattice. The high mica content (e.g. 80-90%) exposes a large part of the surface area of platelets. The max. thickness of finished paper is 100 g/m2. It is strong enough to be taped mechanically and does not need an impregnant.

Title: Spring snap mechanism for hinge - uses filler esp of polyurethane around eccentric part of hinge shaft revolving in tubular housing
Inventor: GRISEBACH HANS-THEODOR
IPC: E05F3/20
Filed: 1972-09-07
Abstract: A spring drive for a snap hinge fitting provides spring forces acting in opposite directions on either side of a dead centre, esp. for hinges with hydraulic braking according to the principal patent.

Title: Lining a container with PTFE foil - as liquid - and gas-proof protection against corrosion
Inventor: SWOZIL ADOLF
IPC: B65D90/08
Filed: 1973-04-14
Abstract: In PTFE-lined containers with connecting pieces having cut-outs, the lining foil is drawn into conical connecting pieces which are firmly joined to the container, subtend an aperture angle alpha and are fitted into the cut-outs.

Title: Input cct. for pulses - pulses received from remote counting device and retransmitted through isolating ccts.
Inventor: MARX JUERGEN
IPC: H03K5/00
Filed: 1973-09-28
Abstract: Input pulses to be processed are applied through a pulse generating threshold switch to the input of an optoelectronic coupling device from whose output the pulses are collected.
